+--  This package provides an Import to the C functions which provide
+--  values related to types on the target system.  It is only needed for
+--  exp_dbug and the elaboration of ttypes.
+
+--  NOTE:  Any changes in this package must be reflected in jgettarg.ads!
+
+--  Note that all these values return sizes of C types with corresponding
+--  names. This allows GNAT to define the corresponding Ada types to have
+--  the same representation. There is one exception to this: the
+--  Wide_Character_Type uses twice the size of a C char, instead of the
+--  size of wchar_t.
